Ferguson Marine Engineering Ltd (FMEL) last month launched legal action against Caledonian Maritime Assets Ltd (CMAL) in a row over a £97 million contract to build two new dual-fuel ferries for the Clyde and Hebrides Ferry Service.
Both ships look set to be months behind schedule.
Central to the dispute is the cost of building the two new ferries.
FMEL claims that the operator has demanded hundreds of design changes.
CMAL insists the work is covered by the original contract.
